Are you facing trials through sickness today? How are you handling it? Can you look at it in a positive light as Paul looked at his sickness, and find some reasons why God may be allowing you to go through these trials?
Or do you look at your sickness the way the world does, the way people who walk in darkness with a Darwinian evolutionary basis of life view sickness?
In this view, God’s plan and purposes are not even considered, and sickness is seen as strictly a physical condition caused by natural forces that can only be cured through the purchase of medicine or medical services.

The idea of our sickness being a result of our sins is not a popular message today, because our humanistic culture is built upon the foundation of Darwinian evolution, and it has taught us to believe that all sickness is a result of natural causes that we can control in our environment.
The drug companies have developed a medicine or vaccine for just about every problem now with this belief system. If they cannot find a cause for the sickness in the natural realm, they usually just cite the cause as "stress" and give a pill for that too.
The spiritual realm, including sin, is usually not even acknowledged. While it is certainly true that our environment, the physical realm, can cause us to be sick, we should first examine ourselves and see if there is a spiritual cause. Sin is very real, and it has very real consequences in our physical bodies. If God is disciplining us through our sickness, then physical remedies (natural or medical) will probably not work.
